When deciding to get your DryCal calibrator recertified, you may notice that Mesa Labs is not the only lab that advertises that it can recertify DryCal instruments. Many third-party calibration labs will perform calibrations on a wide array of instruments. Now, you may think that getting your calibrator recertified at these third-party facilities will give you the same service for a possible lower price compared to factory calibration. However, while both services are called “calibrations”, you are actually receiving a very different service from our factory calibration at Mesa Labs than you would receive at a third-party lab.
What’s in a calibration?
First, we should review what exactly calibration is. Calibration is the relationship between a measurement standard of known uncertainty and test equipment of unknown uncertainty. Calibrations require that you are able to establish a full chain of traceability from your standard to a nationally recognized standard held by an organization such as NIST in the United States. Thus, as long as any laboratory can prove this chain of traceability to a standard with a known and acceptable uncertainty and follow set calibration procedures, they can perform a calibration.
Notice that the calibration described here does not include any adjustment of the instrument. A calibration will note how far the instrument varies from the standard, but the adjustment of the instrument is a different, second process.
Mesa Labs is unique in being able to not only perform the calibration but also to adjust your instrument to bring it back within the tight accuracy tolerances our customers require. In comparison, if you send an instrument to a third-party lab, they can note that your DryCal instrument disagrees with the standard by more than 1%, but they cannot adjust the parameters within the instrument.
Standard Factory Calibration
In addition to the calibration and adjustment, if necessary, our factory calibration includes cleaning and repairs of any worn or damaged components. In the Defender and Definer series, all repairs are included in the flat rate of the recertification cost. No other laboratory in the United States receives parts or is authorized to repair our calibrators.
To ensure your measurements up until this point have been accurate, each calibration certificate provides an “As Received” calibration, showing how the instrument performs when we receive it at our lab in comparison with our traceable standard. Our technicians then perform all cleaning and needed repairs. We then perform an “As Shipped” calibration to ensure all adjustments made in our lab allow you to perform defensible calibrations in your lab and the field.
Our manufacturing and calibration facility in Butler, NJ is an ISO-17025:2005 laboratory accredited through NVLAP. Our flow source provides measurements with up to 0.08% accuracy to ensure you receive the best possible instrumentation and calibrations.

- Notice for our European Customers: Mesa has partnered with TPF Control in the Netherlands to provide full calibration and repairs on our Defender, Definer and older DC-lite and DC1 and 2 models. TPF Control is an ISO 17025 accredited lab and they have received training at our Mesa facility on calibrating, adjusting and repairing our DryCal instruments. Please note that at this time, the metrology series equipment still needs to be returned to Butler, NJ for calibration and repair.
